Application led December 2B, 1904. Serial No. 238,146.

To all whom it may concern: v

Be it known that I, Grenen H. Fonsrrn, a citizen of the United` States, residin at Chicavo, in the county of Cook and State `of Illinois, have invented certain new and useful Improvements in `Metal IVindoW- 4 Sash, of which the 'following is a. specification.

This invention has to do with window sash, but more especially metal sash.

One of the objects of my invent-ion is to provide a sash of the latter type, in which members of the sash proper shall be resilient so as to have spring-pressed engagement with the coperating guides of the window casing, whereby dust is excluded and the sash is prevented from rattling.

I also provide means for adaptin the sash to varying widths of opening o window casings.-

I also provide a simple means for holding the glass securely within the opening of the sash.

Referring to the drawings-Figure 1 is a front elevational view of the sash, provided with a spring counterbalance;- Fig.` 2 is a. fragmentary front elevational view of the sash having a modified form of spring balance; Fig. 3 shows details of a means for fasteiiin the upper end of the spring balance 1n 7, 8, 9, 10, 11 and 12 are detail views showingA various means for adapting the sash to varying widths `oi" window casing; Figs. 13

to 16 show" various means for holding the glass in the sash and providing springpressed engagement between the guiding lmembers of the sash and the coperating guidesof the window casing;l Fig. 17 is an end view of the vertical giudeshowing one way of finishing same, by relatively offsetting the lipped over ends; Fig. 18 is a sectional view showing the offsetting of the ends in further detail. Fig. 19 is a crossscctional detail through the lower bar of the sash and the'lower portion of the glazing. i

1 is the window'casing, 2 and 3 the cross members, and 4 the vertical members of the sash. The sash members are ]o1ned at their corners by. the extensions 6 of the -.back wrlls of the vertical members being l1 pedover and-riveted to the back walls o the cross members; and by the extended sides 7 of the cross vmembers entering within ,l and being riveted to the'ends of the vertical ig. 1 to the casing; Figs. 4, 5, 6,'

members; The extensions 7 are bent inw'ardly as shown in Fig. 17, whereby the vertical and cross members of the sash present an even surface. v

5 is the glass, which is held in position A within the sash.

8 is the actuating spring of the sash balance, which contains the rods 9 and 10. 'lhe latter are lipped over at their respective ends so as to connect the spring at one end to the sash and at the other end to the window casing.' The rod 9 engages the sash through its hook 11 which passes around a pin-l2 carried by the bracket- 13, which is shown as riveted to the rear -walls of the vertical and cross members of the sash. The rod 10 has a hook 14 ada ted to engage the pin 15, which is carried y the bracket 16, as shown in Fig. 3, the bracket being fastened to the window casing by the screw 1T.

The upper portion of the vertical member of the sash is referably provided with a recess 18,- whicli `permits a key 19, after being inserted through the hook 14, Vto be held in a osition. ready for releasing the hook and a lowing the latter to drop and engage the pin 15. This arrangement permits connection of the sash balance between the sash and the window casing after the sash has been introduced in position within the window casing. The ends of the vertical members of the sash are preferably turned over as at 20, presenting two overlappin lips 21 and 22 as shown in Fig. 17 an Fig. 18.

1n Fig. 2 I have shown amodified form of sash balance, in which 23 is a plate fastened to the inner wall of the vertical member and provided with a ton ue 24 adapted to operate within the slot o the tube 25, conltaining the actuating sprin 8a. 'Ilie tube 25 is provided with a base p ate 26, which is fastened to the bottom ofthe window casing.

It must be evident that in either construc' tion', the springs are under their greatest tension when the window-s are down, and that through their tendency to extend, they overcome in a greater or less degree, according to their strength, the weight of the window, thereby enabling the latter to be readily raised to any desired position.

27 is a lock member carried by the sash and 28 a stationary member fastened to the casing whereby the sash may be locked ifdesired in'any adjusted position.

In the various figures showing sectional views of the vertical members of the sash, it should be carefully noted that the distance between the en a ing surfaces of Ithese vertical members i ers when the sash is withdrawn from engagement with the guides of the window casmg from what `it is when the sash is in operation within the window 'i casing. s

In Fig. 16 I show a' protruding guide 29, of the window casing, and in this case the vertical/member, when withdrawn from engagement therewith is transversely narrowed or `diminished in width, which causes the said vertical member, uponv engaging vthe guide, to be expanded laterall under tension. In the other figures an in my preferred form of construction, the vertical guide fiares outwardl so that, when withdrawn, the distance between its enga in surfaces is greater than the inner widt o the groove 30, whereby when the sash is introduced within the latter, frictional lengagement is established between the two. If a metal sash were rovided with transversely yieldable gui es the distance between whose contacting surfaces was the same when associated with and disassociated from the casing guide, a spring-pressed i fit would be impossible unless such enga eeach other throughout their depth of en-` shown I have illustrated the ment were established by contacting t e width ofthe Jgroove in the window casing and thereby the outer edges of the vertical guides of the sash, which would distort the even bearing of the latter, making a line engagement and preventing a uniform surface engagement between the outer portionsl of the vertical members and the guides of the window casing. In my preferred construction, however, the inner width of the groove in the casing is such that when the vertical guidey is introduced therein the cooperating surfaees will uniformly contact agement, thereby most eiiiciently exclud- 1ng the .dust and preventing rattling of the window. In some forms of construction rooves of the window casing as being ma e by the side walls beino' integral with the rear portion thereof, w ile in other forms I make a groove by making either one or both of the side walls detachable from the rear portion thereof.

In Figs. 4, 5, '6, 7, 8, 9, 10, 11 and 12, 1 show various-means for adzpting the sash to varying widths of the win ow casing; the

distance between the guides of window cassl ings, which guides normally consist of grooves, varying considerabl This variation is. easil allowed for inthe case of wooden sash by planing olf the vertical edges of the windowsash, whereas in metal sash this would be expensive and extremely diflicult, and in some cases even impossible, and would at least probably involvedefacement would be danger of the sash being with-' drawn from the groovel first from `the one side and then' from the other.v To prevent this, I referably lip over one or both of the outer e ges of the vertical members and provide grooves either with separate or integral coperating lips. These lips tend lto interlock with each other, and prevent the sash fromy being accidentally Withdrawn from the Qwindow casing. I have SllOWn-the grooves'in window casings made of metal as well as wood lor other suitablematerial. In my` preferred form I make at least one side wall of the groove detachable and where the engaging lips are not integral therewith, I also prefer to makethe latter detachable from the window casing.

In Fig. 10 I have shown only one engaging lipped member fastened tothe casing, but it must be evident that if desired, two could be employed, one on either side of'the groove. It should be noted that in Fig. 10,

the member 31 inclines toward/the yside wall of thev roove, whereby its lip 32 strikes said wall o the groove before the sash is introduced. After the sash has been introduced within the groove and the stop 33 has been screwed into position not only do the vertical members at 34 bear against the sides of thev groove under tension', but the lip 32 of the metal strip 31 bears against the'inner surface ofthe vertical sash member, as indicated in dottedlines, -whereby the entrance of dust is prevented. a l l In the various figures above mentioned which show the lipped edges of the vertical members engaging with 'the coperating lipped locking'members of the casing guide,

I preferably have the said locking members so formed as to engage the sides of the ver tical members underI tension, although it is understood that this is not essential.

In Fig. 9, I not only lip over the outer edges of the vertical sash members but give them a backward turn to coperate with the correspondingly li ped over and backwardly turned members o the guides of the window casing, whereby a still greater closeness ofl engagement is effected In Fig. 12 I show this arrangement of interlocking of sash and casing members, in the case of a sash whose vertical members are not of necessity transversely movable.

In Figs. 13, 14, 15, 16 and 19 I show va-` rious v,constructions of metal strip" for holding theglass within the sash.' 'These strips losn t forward and either held in engagement with.

.are in all cases not integral with the' sash members but separate members and'hold the glass `under spring pressure. 'In the construction shown in Figs. 13, 14 and 15 these strips consist of single pieces and are adapted to be moved in the plane of the sash members, after the glass has been introduced, whereby the more readily to engage the glass. In Figs. 13 and 14 these strlps are adapted to be moved inwardly and 'ontwardly of the glass.

In order to introduce the glass the strips 35 are retracted, after which they are thrust the glass by means of screws 36 or by a rotary key 37. The latter is operated by means of a spindle 38 which is carried by the bear- 'ing 39, the latter being formed by a strip of metal bent and fastened to the rear wall 40 of the vertical member. The key may be operated .by means of a screw-driver used in connection with the slot 41 in the end of the yspindle 38. y

In Fig. 15 the glass, after being inserted, is engaged bythe strip 42, by introducing the latter through the ends of the sash. The V-ways 43 in the sash members hold the engaging portions 44 of the strips 42. In Fig. 1S) I show a means whereby lthe glass may be inserted within the top and bottom glass-engaging strips without the latter being moved relatively to the sash members themselves. TheI glass, as indicated in the dotted lines, is'first inserted within the top strip 45 and is raised up as far as possible. The inside depth of the strip 45 is such that the glass may thereupon be swung, as indicated in the dotted lines, into posltion land inserted within the lower engaging strip 46. `In all the forms vof engaging strips shown I referably form them so that they will positively grip or engage the glass under constant tension, thereby preventing rattling ofthe latter.
